Bioelectric signals are electrical signals that can be generated by living cells, tissues, or organisms. Bioelectric signals can be measured using bioelectric signal sensors, such as electrodes. For example, electrodes can be mounted on the surface of the body to measure various types of bioelectric signals. Bioelectric signals produced by the brain are referred to as electroencephalography (EEG) signals. Bioelectric signals produced by the heart are referred to as electrocardiography (ECG) signals. Bioelectric signals produced by the muscles are referred to as electromyography (EMG) signals. Bioelectric signals produced by the eyes are referred to as electrooculography (EOG) signals.

Products embedded with biosensors can provide value for users in the form of on-demand ubiquitous personal bio-data for health and wellness, entertainment, and/or other uses. As a quickly developing emerging technology, it is not always possible to incorporate the latest personal biosensors into the design cycle of a mass produced product.

What are needed are new and improved techniques for providing biosensors that can be used with existing devices (e.g., portable computing devices, such as smart phones, tablets, etc.).

Accordingly, various techniques for providing a personal biosensor accessory attachment are disclosed. In some embodiments, a personal biosensor accessory attachment system is disclosed. In some embodiments, such a system allows for the convenient addition of bio-sensing capabilities to products, which otherwise lack these features or allows for products with limited sensing capabilities to be augmented.

In some embodiments, a personal biosensor accessory attachment system includes a biosensor for detecting a bio-signal; and a personal biosensor device that is adapted to securely hold the biosensor, in which the personal biosensor device can be adapted to be mechanically secured to a plurality of computing devices (e.g., a mobile computing device, such as a mobile phone or a tablet computer). In some embodiments, the personal biosensor accessory attachment system further includes a fastening device that can be adapted for securely connecting the personal biosensor device to the plurality of computing devices. For example, the fastening device can include one or more additional biosensors for detecting a bio-signal.

In some embodiments, the personal biosensor device further includes a display output for providing an output feedback for bio-signal related information measured using the biosensor. In some embodiments, the personal biosensor device further includes an audio output for providing an output feedback for bio-signal related information measured using the biosensor. In some embodiments, the personal biosensor device further includes a communication mechanism for providing wired or wireless communication based on bio-signal related information measured using the biosensor to the computing device. In some embodiments, the personal biosensor device further includes a communication mechanism for providing wired or wireless communication based on bio-signal related information measured using the biosensor to a cloud-based bio-signal monitoring service.

In some embodiments, the personal biosensor device that is adapted to securely hold a plurality of biosensors includes one or more of each of the following types of biosensors: an electroencephalography (EEG) sensor, an electrocardiography (ECG) sensor, an electrooculography (EOG) sensor, an electromyography (EMG) sensor, and a galvanic skin response (GSR) sensor. In some embodiments, the biosensor includes an EEG sensor, in which the EEG sensor includes a stainless steel passive, dry biosensor. In some embodiments, the biosensor measures an EEG signal, in which the EEG signal is processed to determine a user's mental state (e.g., whether a user is in a focused state or in a relaxed state).

FIG. 1 illustrates a personal biosensor device in accordance with some embodiments. As shown, the personal biosensor device includes biosensors (e.g., bio-signal sensors) for EEG, ECG, EMG, blood oximetry, and/or other types of biosensors; a user feedback mechanism in the form of a screen display (e.g., an LCD screen), LEDs, vibration, and/or an audio speaker; the ability to communicate with other devices through a physical port, such as a USB or wirelessly through radio frequency or infrared (e.g., Bluetooth wireless communication standard or other wireless communication standards or protocols). In particular, the personal biosensor device is designed to be mechanically secured to another accessory, which will change the specific utility scenario of the sensor unit. For example, the sensor unit can be secured to a mobile phone (e.g., a smart phone), to a chest strap for sensing ECG, or to a clip, which can allow the user to fasten the sensor unit to an article of clothing. As another example, the sensor unit can be secured to a watch, a keyboard, an article of clothing, or a piece of jewelry (e.g., a bracelet that a user wears on their wrist).

As shown in FIG. 1, the personal biosensor device includes a bio-sensor or bio-sensors (e.g., ECG, EEG, EMG, blood oximetry, and/or types of biosensors) (101), a user feedback mechanism (e.g., LCD Screen, LED array, audio speakers, and/or other output mechanisms) (102), and communication equipment for sending bio-signal data to another device (e.g., USB port, pin contacts, and/or wireless radio frequency, such as Bluetooth and/or other protocols/standards for wireless communications) (103, 104). For example, the biosensor device can also include an internal flash memory and/or processing capability. In some embodiments, the form factor of the biosensor device is designed to allow mechanical fastening directly to another product or with a specifically designed fastening device.

FIG. 2 illustrates a method for a sensor unit to be attached to a mobile device, which it communicates with by utilizing a third mechanical part to fasten it within close physical distance in accordance with some embodiments. For example, the mechanical fastening device can be a cast silicon or rubber part or have embedded sensors and other electronics, which can connect to the sensor unit and assist in gathering or displaying bio-signal information. The fastening device securely holds the biosensor device.

In particular, FIG. 2 illustrates the assembly of the sensor unit (201), mobile device (203), and fastening device (202) used to keep the sensor unit and the mobile device in close proximity to facilitate wired or wireless communication. The fastening device may not be necessary in all embodiments or user interaction scenarios. For example, the biosensor device can be used by itself, or the biosensor device and mobile device or other computing unit can be geographically separated. The fastening device can also secure the biosensor device to another mobile or computing device. As another example, the fastening device can only be a clip that helps the user fasten the biosensor device onto clothes. As yet another example, the fastening device can be in the form of a strap, which would help ensure constant sensor contact on the user's chest, limb, head, or other location of the user's body.

In some embodiments, there is no fastening device, and the biosensor device communicates directly to a mobile or other computing device through a USB cable, wireless RF, or through an Internet-based cloud service. In some embodiments, the sensor device or fastening device interacts directly with the mobile device or each other as a source of power (e.g., extra battery, wireless magnetic induction charging, solar charging, or kinetic charging) or includes memory, which stores bio-signal data and/or miscellaneous user data in the same manner as an all-purpose USB memory stick. For example, transfer of data to the sensor device or fastening device with additional memory capability is not limited to physical interfaces like a USB stick and can include wireless data transmission, such as radio frequency (e.g., Bluetooth), infrared light, or digital audio pulses.

In some embodiments, a fastening device is passive without any electronics or sensor contacts. In some embodiments, a fastening device is active with sensor contacts and/or electronics. For example, the display, audio, communication and power supply/recharging, and/or other functions can be on the biosensor device and/or the fastening device. In some embodiments, the fastening device performs one or more active functions, and an electrical connection between the biosensor device and the fastening device can be through dedicated connectors and/or through the sensor contacts on the biosensor device.

FIG. 3 illustrates the sensor unit, mobile device, and fastening device assembled together in accordance with some embodiments. As shown, there are additional sensors on the fastening device, which connect to the sensor unit to enhance or change the nature of the bio-signal captured. The additional sensors connect physically to the sensors on the biosensor device through extended electrical leads. In some embodiments, sensors are provided that connect to the communication port of the biosensor device or wirelessly.

In particular, FIG. 3 illustrates the biosensor device (302), mobile device and fastening device (301) assembled together. Additional sensors (303, 304) on the fastening device connect to the biosensor device through a physical electrical or wireless digital connection. In some embodiments, the fastening device is inert with no sensors or embedded electronics. Sensors on the fastening device may differ from those on the biosensor device. For example, the biosensor device can include ECG sensor(s) while the sensors on the fastening device can include EEG sensor(s). Sensors on the fastening device can also increase the capabilities of the biosensor device by adding additional sensors of the same kind (e.g., adding additional EEG sensors to allow for more complex algorithms to be used) or be made from different/superior materials to influence the quality of the bio-signal captured.

FIG. 4 illustrates a configuration of the sensor unit, mobile device, and fastening device in use (e.g., or just the sensor unit by itself) in accordance with some embodiments. As shown, the user can touch two bio-sensor pads. For example, the sensor unit can communicate the collected data to the mobile device for display or to be stored, and the sensor unit can also display the bio-signal data on the sensor unit itself.

In particular, FIG. 4 illustrates one use case scenario in which the user touches two ECG biosensors with their thumbs on the biosensor device (401), which is attached to the back of a mobile phone. As shown, an LCD screen on the biosensor device gives the user visual feedback on the user's heart rate measured using the two ECG biosensors. The biosensor device can be used alone or attached to another device. The fastening device (402) is optional in this case. In some embodiments, the biosensor device displays complex graphical representations of the bio-signal information, simple LED lights and patterns or audio tones, vibrations, heat, music, or voice to convey meaningful feedback to the user.

FIG. 5 illustrates a configuration of a personal biosensor device in which the user touches bio-sensors located on the mechanical fastening device that connect back to the sensor unit in accordance with some embodiments. As shown, the sensor unit collects the bio-signal data from the sensors on the fastening device and sends the data to a mobile device for display.

In particular, FIG. 5 illustrates another scenario in which the user contacts bio-sensors (501) located on the fastening device to facilitate a different hand orientation when using the device. The bio-signal data is collected by the sensors on the fastening device, communicated to the biosensor device, and sent to the mobile device. The mobile device processes, stores, and displays the bio-signal information (502) to the user. For example, bio-signal information can be displayed on the device in closest proximity to the biosensor device or with other mobile devices simultaneously over wired, wireless, or Internet communications. In some embodiments, the bio-signal sensors are positioned or located on the fastening device so as to facilitate contact with different areas of the user's body or be designed to contact multiple individual users at once.

FIG. 6 illustrates a configuration of a personal biosensor device in which a sensor on the fastening device is located such that it contacts another area of the human body of a user instead of the hand of the user for passive data collection while the user is actively engaged in another activity in accordance with some embodiments.

In particular, FIG. 6 illustrates another configuration in which the biosensors are located on the fastening device, but positioned so that the location of the biosensors facilitates contact with the user's face (601) when the user is holding the mobile phone for a phone call. Additional sensors on the fastening device collect ECG data when the user is actively engaged in talking and not viewing the data.

In some embodiments, the fastening device is designed to facilitate placing the sensor unit on a chest strap, clothing, hat, gloves, shoes, and/or other personal apparel or articles of clothing. In some embodiments, the fastening device is designed to facilitate placing the sensor unit on stationary devices that the user comes into contact with, such as exercise equipment, vehicle steering wheels, furniture, or architectural features such as door handles or floors.

Although the foregoing embodiments have been described in some detail for purposes of clarity of understanding, the invention is not limited to the details provided. There are many alternative ways of implementing the invention. The disclosed embodiments are illustrative and not restrictive.
